TYPOGRAPHICAL MACHINE.

To all whom it may concern Be it known that I, BRUNO BLOCH, a subject ofthe German Emperor, residin at 23 Chausseestrasse, Berlin, N. 4, in thempire of Germany, have invented new and useful Improvements inTypographical Machines, of which the following is a specification.

The present invention relates to an arrangement, by means of whichmachines operated manually through a key board, especially matrixcomposing and line casting machines may be driven at times mechanicallyby means of a perforated strip. It has already for this purpose, beenproposed to release electrical contacts by means of a perforated stripand thus operate upon the keys of matrix composing machines through themediation of electromagnets. This arrangement however has thedisadvantage of bein extremely complicated and sensitive and thereforeunreliable. According to the present invention a mechanism independentof the machine itself, and controlled by a perforated strip of paper isprovided, to be applied at will to the machine so as to effect amechanical operation of the key mecha-' nisms. It may operate upon anymembers of the latter.

Referring to the drawing: Figure 1 is a vertical section taken throughthe key board mechanism of a linotype machine, and showing my inventionapplied thereto; Fig. 2 is a side elevation, partly broken away, of myimproved mechanism; Fig. 3 is atop plan view of the parts shown in Fig.2; and Fig. 4 is a detail view. 1

a are the keys by which in the known manner through mediation of theescapement rods 6, the escapements 0 can be operated.

According to the invention, and in a covering box not shown in thedrawing, a series of levers d is suitably fulcrumed on the axis 6, theirfront ends projecting out of the covering box, so as to be able toengage notches n in the escapement rods b. Each of these levers d has areleasing pin 7. The perforated strip of paper g is passed around aguide roller is, and overthe the pivoted levers d, so as to locate itsperforations above the releasing pins f of the levers. This strip hasthe width of the key board and is moved intermittently by a pawl andratchet arrangement 0 operated by a came on the driving shaft p of themachine. The

strip is moved along by the driven roller in the known manner by meansof sprocket ration 1n the edges of the strip. The levers d are pulledupward by the springs b. so as to bear against the perforated strip. In

order to prevent the latter from being pushed away, a counterpart i isprovided which has holes at the parts opposite the pins f, into whichholes these pins can enter, if the strip 9 happens to be perforated at acorresponding place. Durin each advance ofthe perforated strip 9 allevers d are once moved upa'nd down by the cam disks 70 arranged at theopposite ends of the guide roller k for the strip. To this end, asuitably-guided bar m is provided,.extending over the levers d andhaving upwardly proecting studs m engaging the toothed shaped cams onthe cam disks k.

engaging continuous rows of perfo- The improved mechanism works asfollows :--The perforated paper strip advances intermittently to theextent of one section.

Each section has ahole in a position to cor-' respond with the letter tobe used. During the movement of the strip 9, all the levers (Z are heldout of contact with the perforated strip by the action of the cam disksin on the bar m. After the advance of the strip g, the studs on the baron enter depressions of the cams k, so that the levers d are able tomove upward, and the lever whose pin 7 is then opposite the hole in thestrlp g is raised by the spring 72. to such an extent as to lift theescapement rod 7). Each escapement rod is formed with a notch 11. ofsuch dimensions as to allow the corresponding lever d when not thusreleased to move under the action of the cams k without impartingmovement to the rod. Y

The whole casing within which the releasing device is arranged is madeso as to be easily aflixed to the machine to be operated,

so that the machine may at will be changed from a hand machine into anautomatic mama chine.

Having described my invention, I declare that what I claim and desire tosecure by Letters Patent is 1. Alternative perforated strip mechanism105 for operating a machine fitted to be operated through a manuallyoperated key board, consisting of a perforated strip, means foradvancing it with a step by step.1 motion; releasing studs moved towardt e said strip after each advance; means for so-moving them and causingone of them to ass through the respectively opposite per oration; andmeans by which the movement of that passing through actuates therespective key mechanism of the machine.

2. Alternative perforated strip mechanism for operating a machine fittedto be operated through a manually operated key board, consisting of aperforated strip; means for advancing it with a step by step motion;releasing studs moved toward the said strip after each advance; meansfor so moving them' and causing one of them to pass throughtherespectively opposite per. foration; means for moving all the studs awayfrom the strip before each advance of the latter; and means by which themovement of that passing through actuates the respective key mechanismof the machine.

3. Alternative perforated strip mecha-' nism for operating a machinefitted to be 0perated through a manually operated key board, consistingof a perforated strip;

means for advancing it with a step by step motion; releasing studs movedtoward the said strip after each advance; levers carrying the saidstuds; means for so moving the said levers and studs and causing one ofthe studs to pass through the respectively opposite perforation; meansby which the respective lever operates the respective member of thekeymechanismsynchronously with the passage of the stud through theperforation; and means for returning the levers without affecting theunoperated members of the key mechanism.

4. Alternative perforated strip mechanism for operating a machine fittedto be operated through a manually operated keyboard, consisting of aperforated strip; means for advancing it with a step by step motion;releasing studs moved toward the said strip after each advance; leverscarrying the said studs; a frame supporting the said levers andoscillated vertically by the strip feeding means; means for so movingbination of a series of escapement actuatingv the said levers and studsand causing one of the studs to pass through the respectively oppositeperforation; means by which the respective lever operates the respectivemember of the key mechanism synchronouslv with the passage of the studthrough the perforation; and means for returning the levers withoutaffecting the unoperated members of the key mechanism.

In a typographical machine, the com bination of a series of escapmentactuating devices, a corresponding series of members tending constantlyto operate said devices, releasable means for holding the membersagainst operation, and a perforated strip mechanism to control theoperation of said members when released by the holding means.
